WILLIAM H. GOSS, OF FRANKLIN TG'WNSHEP, SOIEERSET COUNTY, NEW JERSEYJGAS-GENERATING BURNER.

Application filed February 8, 1926.

This invention relates .to gas-generating burners, and the objects ofthe improvements are, first, to provide forthe simple and economicalcasting of the device in a single piece, thereby eliminating amultiplicity or separate parts and providing a stronger, better, andmore lasting structure; second, to provide for the prompt and thoroughgeneration of gas by the efficient application of heat on the generator;and third, to prevent flooding of the device and he consequent waste ofoil by the automatic control of the oil feed. v

I attain these objects by the structure illustrated in the accompanyingdrawings wherein V Figure lis a. plan view of the device; Figure 2, avertical longitudinal section of the same; Figure 3, a cross section online 3-3 of Figure 1; Figure 4, a cross section on line 4-4 of Figure 1;Figure 5, an enlarged detailed view of the needle valve; and Figure 6, adetailed view in top plan of one end of the gas-generating cylinder,depicting a part of the float valve mechaniSm.

Describing the invention in detail, 1 des ignates the base of thedevice, which is relatively long and narrow, and provided with a flatbottom in order to rest firmly and easily upon the grate of the stove orfurnace in which the device is placed. To further increase the stabilityof the device, supporting lugs 2 are provided at each corner of the baseand project upwardly on opposite sides of the latter. Above the base andin line therewith is a hollow, barrel-shaped cylinder 3 in which gas isgenerated as hereinafter explained. This gas-generating cylinder issupported at its ends-upon short vertical extensions 1 -l rising fromthe er;- tremities of the base, as illustrated.

An auxiliary burner 5 extends along one side of the cylinder 3, andsubstantially in line with the bottom thereof, being joined thereto bythe inturned portions 66 wl'iich are slightly inclined with respect tothe horizontal, as seen in Figures 3 and at. The base, cylinder, andside burner are preferably cast in one piece and the construction is sodesigned as to permit this to be easily accomplished, it being found inpractice that a casting is more desirable than piping owing to itsgreater heat-resisting properties and the fact that it will not,therefore, burn out so quickly when sub- Serial No. 86,888.

jected to the intense flame and heat from the burner jets.

Fuel oil from a supply source is conducted by suitable piping to theinlet passage '7 leading inwardly of the vertical base extension t andcommunicating "with the central passage 8 of the latter. Passage 8 opensoutwardly through the base 1 and has its upper terminal. communicatingwith a large opening 9 provided in one end of the cylinder 3. vided inthe opposite end of the cylinder, and threaded plugs 11 and 12 areinserted in the outer ends of the openings to close the same. Opening 9constitutes the oil inst to cylinder 3 and has a short bottom groove 13from which the oil from passage 8 is permitted to flow and drip into thecylinder in small quantities at a time. Opening 10 constitutes thegas-outlet of the cylinder and is in communication with the verticalcentral passage 1a of the base extension 4t, which passage likewise hasits bottom opening in the base 1. Extending clear through the base andintersecting passages 8 and 1a is a central longitudinal bore 15 interrupted at one or more points by vertically disposed burner jets 16having needle valve control 17. The bottom openings of passages 8 and 1aare closed by plugs 18 and 19, and the terminal ends of the base passage15 are closed by plugs 20 and 21. All of these'plugs are removable topermit access to the passages for purpose of cleaning, etc., and inorder to prevent the oilt'rom the inletpassage 8 from backing into thebase passage, an internal plug 22 is adapted to be screwed or otherwiseengaged in the vertical passage 8 just below the inlet "2'.

The side btrner 5 is cast solid in part, as shown at 23, and has theremaining part cored to provide a by-pass from the gas passage let ofthe base extension at, which.

b-y-pass consists of the intersecting passages 2% and The outer ends ofthese intersectingpassages are closed by removable plugs 26 and QT.Passage 25 is provided with one or more burner jets 28 having needlevalve control 29 and disposed in an inclined plane so as to direct theflame against the bottom and to the opposite side of the gas cylinder.This arrangement is of particular advantage in connection with stoves orfurnaces having the fire-box enclosed by a water-jacket, and in placingthe improved device in such a stove or furnace,

A similar opening 10 is pro ill) it will be placed with the burner-lessside of the gas cylinder disposed against one side of the water-jacketso that the flame from the side burner, after passing beneath thecylinder, will impinge the jacket walls and be thus applied direct tothe jacket. Any number of gas burners may, of course, be used, accordingto the size of the furnace and capacity of the individual burner.

In order that the oil may be quickly and thoroughly converted into gas,only a small quantity at a time is admitted into the gas cylinder, andthe feed is regulated in part by a float-controlled valve and in part bythe pressure of the generated gas. The valve mechanism consists of 2.long needle valve 30 extending downwardly for a apprcciable distanceinto the inlet passage 8, and having at its lower end the usual needlepoint 61 adapted to engage the valve-opening 32 in the valve seat 33.The valve seat is threadedly engaged in the passage 8 just above theinlet 7 and is removable through the bottom opening of the passage whenthe plugs 18 and 22 are taken out. Valve 3 has a bracket swiveled to itsupper end and presenting spaced upstanding arms a and 6 connected by apin 0 adapted to engage in a slot d formed in one end of rod 34;, fromwhich the valve is suspended. By means of this arrangement, the valvehas a tree swinging movement for self-seating purposes as it isloweredonto its seat. 0d 3% extends inwardly of the cylinder for nearlythe entire length of the same and is pivoted at 36 to a. plug 87removably fitted in opening 9 of the cylinder. A. float 38 is suspendedfrom the free end of the rod and normally rests on or very close to thebottom of the cylinder. A plug 39 engaged in opening 10 of the gascylinder and extending inwardly thereof, has its inner portionbifurcated vertically to provide spaced guide fingers 40+l0 adapted toextend on opposite sides of the free end of the float rod. Top andbottom grooves 4-1 are formed in the body of the plug and communicatewith the vertical passage 42 ot' the plug, which passage is in line withthe gas pas sage 1-loi the device.

In the operation of the device, the float is adapted to be lifted by theinflow of only av small amount of oil, and the needle valve is adjustedand arranged to close when the float is slightly elevated, thearrangement being such that at no time will the cylinder contain anygreat amount of oil. The base 1' of the device has its surface groovedto provide a priming pan or trough -l3 and in starting the device thispan is filled with gasoline or other priming material which is ignitedto preheat the cylinder. As the cylinder becomes heated and the oiltherein gasified, the gas vapors escape through outlets ti and t2 intothe gas passage 1% from whence they are conducted to burners l6 and 28.When the level of the oil lowers in the cylinder, due to thevaporization thereof, the float. drops and opens the needle valve 30.The pressure within the cylinder would normally prevent any oil fromfeeding into the cylinder, but as this pressure is diminished constantlyby the escape oi 'as at the burner outlets, the oil is permitted to dripfrom groove 13 and becomes vaporized as it falls in contact with theheated bottom of the cylinder, against which the flames from the burnerjet are directed In the even; of the flames becoming extinguished, withthe resultant cooling of the cylinder, and the loss of pressure therein,the flooding of the entire device is prevented by the action of thefloat, which, upon the entrance of a small quantity of oil in thecylinder, is elevated the slight degree necessary to close the needlevalve and shut otl' further flow of the oil.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:
